What affects the quote in Over Wallop
We do not publish a price list, because jobs vary so much. The quote depends on:
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
- Working hours on commercial sites
- The number of rooms or windows
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote

- A few photos by email, if you can

Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Floor joint sealing in Over Wallop
Where skirting is painted, we can use a flexible sealant that takes paint. In wet areas we’d normally use silicone, which isn’t made to be painted. We work on wet room & bathroom floors, skirting boards and concrete floor joints, and common reasons people get in touch are chipped and open joints in warehouse floors and dirt and water collecting in open floor joints.
Older homes in small places like Over Wallop often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Our work is backed for twelve months, in Over Wallop and everywhere else we cover.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Avoid sloshing water against skirting
- Check the sealant is paintable before decorating
- Vacuum floor joints regularly to stop grit building up
- Keep caulk for dry, still joints only
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Cone off the area if needed until it’s ready.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.
Floor joint sealing around Over Wallop
Across Hampshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal.
If you let a flat or house near Grateley station, gaps at skirtings and thresholds are worth sealing between tenancies. For site and facilities teams at buildings such as Wallop Primary School, entrance and corridor floor joints take a lot of traffic.

How the visit works

We bring what the job needs, so it can be finished in one trip where possible.
- We look at the gap and the floor type and agree the right sealant.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
How to prepare
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

Common questions in Over Wallop
Can you do floor joint sealing in Over Wallop?
Yes, Over Wallop is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Do you cover smaller places like Over Wallop?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we will agree it with you first.
How long before the joint can take traffic?
We give you a cure time for each joint. Feet are generally fine first, then mopping, then heavy wheels.
My floor grout keeps cracking in a line. Can you help?
Often, yes, where it suits the floor. The grout is raked out and replaced with a flexible sealant in a colour to suit.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Where do you work from?
Mr Mastic is based in Crawley. We cover Over Wallop and the rest of Hampshire, along with the rest of our area.
How much does floor joint sealing cost in Over Wallop?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Why deal with it now?
Floor joints left open collect dirt that’s hard to clean out. A neat sealed joint is easier to clean. Older cottages and farmhouses around Over Wallop can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

What we’re called out for in Over Wallop
A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting and anything rigid cracks.
People usually contact us after spotting something like this:
- Grout used at the floor edge instead of sealant
- Failed seals where bathroom floors meet baths and panels
- Grout cracking in a straight line across a floor
- Dirt and water collecting in open floor joints
Community buildings like Church of St Peter are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
